Equipment damage due to improperly connected coolant pipes!
If the coolant pipes are not properly connected or a gas-cooled welding torch is used, the coolant
circuit is interrupted and equipment damage can occur.
• Connect all coolant pipes correctly!
• Completely unroll the hose package and the torch hose package!
• Observe maximal hose package length > see 5.1.5.2 chapter.
